DOUBLE-DISK DRILL.

SPECIFICATION forming part of .Letters Patent No. 734,018, dated July21, 1903. Application filed April 17, 1903. Serial No. 153,139- (Nomodel-1 1'1) all whom 2125 may concern:

Be it known that LWILLARD A. VAN BRUNT,

a resident of Horicon, in the county of Dodge and State of Wisconsin,have invented certain new and usefulImprovements in Doublebearings forthedisks which will permit of ready access to the parts for cleaningthem or removing broken or worn parts and their replacement by newparts.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of Y parts,as will be more fully hereinafter described, and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a view in side elevation,partly broken away, illustrating my improvements; Fig. 2 is a top planview. Fig. 3 is a detail view of the inside scraper. Figs. 4and 5 areviews illustrating the disk-bearings, and Figs. 6 and 7 are similarviews of a modified form of bearing.

1 represents the disk-frame, which comprises a curved plate 2, having anenlargement or block 3 at its forward end, a vertical hollowlubricant-conducting standard 4 between its ends, and suitableperforated ears for the attachment of the ordinary drag and liftingbars, and a suitable seed-tube 5 is provided for dropping the seedbetween the disks.

The standard 4 is provided in opposite sides near its lower end withscrew-threaded openings communicating with the lubricant-duct therein,and hollow screw-threaded lugs 6 on' bearing-blocks 7 are screwed intosaid openings, the threads of the lugs being,.respectively, right andleft, so that the rotation of the disks tends to tighten the bearings inplace.

The bearing-blocks 7 have contractedjournals 8, on which the disks 9revolve, and my improved bearing-cups are secured to the disks and turnon the blocks, as will now be explained.

The cups each comprise two members, one member 10 being aninternally-screw-threaded ring having integral lugs or rivets 11 aroundits inner edge to enter openings in disk 9 and be upset orsecurelyriveted'therein. The other member12 is saucer-shaped andexternally screw-threaded to screw into member or ring 10 and turn onthe block.

Washers 13 are preferably placed on blocks 7 between them and the disksto prevent Wear of the disks and block, and a lubricant receptacle orpocket 14 is made in each block to receive the lubricant from standard 4and supply the same to the bearing, and suitable sockets 15 are providedin the removable members 12 to permit the employment of a spanner-wrenchto remove orreplace them.

In Figs. 6 and 7 I illustrate a modified form of bearing in which thelugs 6 are dispensed with, and alined openings are made in standard 4for the passage of a headed bolt 17, and bearing-blocks 16 are securedin place by said bolt and a nut 18.

Instead of internally screw-threading the ring 19 I provide the samewith internal camflanges 20, spaced apart to permit the entrance of lugsor flanges 21 on the removable member or cap 22, so that when the cap 22is placed in position with its-lugs or flanges 21 below cam-flanges 20and is given a partial turn it will be efiectually secured in place. Thecamfianges are sodisposed that the turning of the disks tends to tightenthe cap in place.

While I have in both forms of bearing'illustrated the removable memberas being on the bearing-block, it is to be understood that I do notconfine myself thereto, as the member fixed to the disks may form thecomplete bearing and the removable member be merely a closure therefor.

In the block or enlargement 3 at the forward end of the frame 1 anapproximately vertical opening is provided to receive a pin 23, having aflat circular perforated head at its upper end to receive a bolt 24,also passed through openings in the forward ends of spring-arms 25,located on opposite sides of pin 23 and secured thereto by an ordinarynut. These spring arms 25 bow outward around plate 2, which it will beobserved projects at both sides beyond the outer face of the disks. Therear ends of arms 25 are bent inward and have plates or scrapers 26secured thereto and adapted to bear against the outer faces of the disksand effectually clean them.

To regulate the tension of the spring-arms, I connect them between theirends by a bolt 27, also passed through an elongated slot 28 in frame 1to permit pivotal movement of the arms on bolt 24 to dispose thescrapers against the edges of plate 2 and hold them out of c011- tactwith the disks when working in soil in which the scrapers are not neededor for any other reason it may be desired that the scrapers be idle.This pivotal movement of the arms 25 on bolt 24 also enables thescrapers to be moved nearer to or farther from the edge of the disks,and the rotary support of pin 23 in block 3 compels uniform pressure ofthe scrapers on both disks.

In a depending arm 29 on the rear end of frame 1 a hollow-headed sleeve30 is located and is internally screw-threaded to receive a headedscrew31,which latter engagesascraper 32, composed of spring sheet metalbent longitudinally and having its end portions engaging the sides ofarm 29, so that when the screw or sleeve is adjusted the scraper will bewidened or contracted to elfectually scrape the inside of the disks.

A great many changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot confine myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a disk drill, the combination with a support, of a bearingblockremovably secured to the support, a disk turning on said block, and abearing-cup turning on the block and comprising two members, one securedto the disk and the other removably secured to the first-mentionedmember to permit the removal of the bearing-block without disconmeetingthe first-mentioned member from the disk.

2.
